With the development of China's highway construction, rural road construction has taken more and more attention by state and local governments, how to further enhance the rural highway pavement performance gradually become the concern of all parties. As rural road construction has always been difficult problems facing scarcity of investment, the design flaws often leading to premature disease in the road.This paper summarized the state and several provinces and cities of rural roads and representation road design standards, after comparative analysis with the Actual situation of Tangshan City, Proposed the road design standards of Tangshan. Comprehensive survey the overall status of rural roads of Tangshan city, Analysis the traffic characteristics and problems exist. Determinate that the typical road structure design of Tangshan City need to be targeted on the imbalance of traffic for rural road in Tangshan City.This text summarized the research status of road structure design methods in domestic and international, combine with the traffic conditions, the existing road structures and type of materials and the located geology and hydrology data, and then the traffic and soil-strength were graded, finally the typical road structure of Tangshan City was proposed.Tangshan City is a heavy industry city, large number of industrial waste if not properly handled will cause great negative impact on the environment, this test research form the principle of obtain material from local sources, consider of save money and environmental protection, try to study on the feasibility of using the tailings on the asphalt mixture, through the lab trial and determined that is feasible. Also in this paper, the conservation and management of rural road surface have been studied, for the common management of road maintenance and road disease, then brought the corresponding treatment.
